Optimal Design of Anti-Collision Spacer Ring for Power Transmission Lines

Electrical power transmission relies heavily on power transmission lines. The swinging of the lines during windy weather can cause conductor collision between adjacent lines, which can result in severe electrical accidents. To solve this problem, this paper proposes an anti-collision spacer ring and its structure optimization method. Topology optimization, as a structural optimization method, is used to design the spacer ring to achieve maximum stiffness and minimum mass. The model is redesigned based on the optimized results, and its performance is subsequently assessed through static analysis and electrostatic field analysis. The results before and after optimization show that the maximum equivalent stress on the spacer ring is reduced by 34.4% and the mass is decreased by 10.5%. It realizes the lightweight design of the spacer ring, and provides theoretical basis and technical support for the structural design of the spacer ring.
